摘要：
Electroluminescent devices using new iridium complexes (see Figure) (PEQ)(2)Ir(acetylacetonate (acac)), (MPEQ)(2)Ir(acac), and (PEIQ)(2)Ir(acac), as dopant emitters give saturated red light with very high brightness and efficiencies. For example, a (PEQ)(2)Ir(acac)-based device showed Commission Internationale de L'Eclairage (CIE) coordinates (0.66, 0.33), brightness, and external quantum efficiency of 26400 cd m(-2) and 7.23%, respectively.
